Clear all local messages

Clear all message records stored in the local SQLite database for the current logged-in account on this device:

await OpenIMSDK.deleteAllMsgFromLocal();

Return value

A resolved Promise confirms that all message records in the local database on the current device have been deleted. Historical messages remain preserved on the server.

This is an irreversible, account-level local action. Before executing, explain the impact clearly to the user and require secondary confirmation. This operation modifies only local device storage; it does not affect other active sessions or trigger multi-device deletion events. Clear local conversation lists and view caches in the client UI accordingly.
